CHAPTER 16: DEBUGGER
Notes: • The bus break function cannot be used in the ICD, ICE, debug monitor, and simulator modes.
Forced break by [Key break] button
Note: This break function is not available in the debug monitor mode.
Pulling S5U1C33104H BRKIN pin low (only in ICE or ICD mode)
Notes: • This function is not available in the debug monitor and simulator modes.
Map break and break by executing illegal instruction
Note: The following break functions are not available in ICD and debug monitor modes.

(1) Write to data ROM area
(2) Access to no-map area
(3) Accessing outside stack area (only in ICE mode)
When using the bb command, follow the instructions shown in the [Command] window as you enter the
break conditions. The address can also be specified using a symbol.
The [Key break] button can be used to forcibly terminate the program under execution when the program
has fallen into an endless loop or cannot exit a standby (HALT or SLEEP) state.
The program is made to break by entering a low pulse to the S5U1C33104H/S5U1C33000H BRKIN pin
when operating in ICE/ICD mode.
When this break occurs, the db33 displays the following message in the [Command] window and stands by
waiting for command input.
The program also breaks when one of the following errors is encountered during program execution:
A break occurs when the program writes data to the ROM area set by the parameter file.
When this break occurs, the db33 displays the following message in the [Command] window and stands by
waiting for command input.
A break occurs when the program accesses a no-map area that has not be defined in the parameter file.
When this break occurs, the db33 displays the following message in the [Command] window and stands by
waiting for command input.
A break occurs when the program accesses an area outside the stack area using the SP.
This break will occur only in ICE mode.
When this break occurs, the db33 displays the following message in the [Command] window and stands by
waiting for command input.
• In the S5U1C33000H, there is a delay time of approximately 1.5 µsec between a pulse input to
• A break by S5U1C33001M1 using S5U1C33000H external break occurs after the memory is
the BRKIN pin and the actual break generation.

accessed a few times when you access the break conditions. Therefore, a break occurs not
just after the specified memory is accessed.
